JOHN F. MOORE, OF FORT WORTH, TEXAS, ASSIGNOR TO THE FORT WORTH IRON\VORKS COMPANY, OF SAME PLACE.

WELL-DRILLING MACHINE.

SPECIFICATION forming part of Letters Patent No. 384,994, dated June 28,1888.

Application filed September 28, 1887. Serial No. 250,919. (No model.)

To all whom it may concern.-

Be it known that 1, JOHN F. MOORE, acitizen of the United States,residing at Fort Worth, in the county of Tarrant and State of Texas,have invented a certain new and useful \Vell-Drilling Machine, of whichthe following is a specification.

My invention relates to improvements in well-drilling machines in whichthe various devices for drilling, lowering, and raising the drill andlowering and raising the sand-pump are placed together upon the sameframe; and the object of my improvements is to so arrange the levers andmechanism that the several parts of the machine may be operated orcontrolled by one person in front of it. I attain these objects by meansillustrated in the accompanying drawings, in which- Figure 1 is aperspective view of the machine, and Fig. 2 is a plan view of the same.

Similar letters refer to similar parts throughout the several views.

The frame B B supports the various shafts and drn ms of the mechanism,which are jou r naled in bearings bolted in its upper and lowerhorizontal beams. To the middle of one end of the frame is bolted theupright A, carrying the pulleys T for the drill-rope S, and the pulley Vfor the rope U of the sand-pump, indicated by V7. The shaft X is causedto revolve by any suitable connection at either end with a motor. Onthis shaft is gear mimeshing in gear a, thelatter being on the sameshaft with the counterbalancewheel I. On the middle of shaft X is a camor arm, J, having autifriction rollers j 3'. These rollers j j arearranged at an angle of about forty-five degrees to the arm or cam J,which arm is bent and forms suitable journal for both rollers. Thisarrangement and construction renders the movement of the arm, on thebeam K easy and obviates pounding.

The revolution of shaft X causes the cam J to alternately depress beam Kand then allow it to rebound by the effect of the weight of the drill,thereby raising and dropping the drill. The clutch P is keyed solidly toshaft X, and the pulley I is loose on said shaft. Cast solid with pulleyI are ratehctteeth interlocking with clutch-wheel I. The pulley I ismade to interlock with I? by a compound lever, to Z) c,

operated by handle at at the front of the machine. W'hen pulley "I islocked with clutch P, the belt 0 causes a pulley, F, to revolve, and

thereby also its shaft, which also carries the 3 5 H sand-pom p rcel G.The brake q of the sand-, pump reel is operated by placing the foot upontreadle 1), thereby moving levers n n.

Exactly similar to P and F is the operation of sprocketwheel H andclutch O, the former 6;) being loose upon shaft X and the latter keyedto it. \Vhen the ratchet-teeth formed solid with H are interlocked withclutch O by. means of compound leverff, operated by the handle g, therevolution of sprocket-wheel H causes the chain belt or sprocket-chain hto revolve sprocket-wheel E. This wheel E and spur-gear E are solid onthe same shaft. The revolution of spur'gear E causes gear-wheel O torevolve and also the drill-rope drum 1) 7t on the same shaft withgear-wheel 0. Cast solid with E is a pulley-rim, m, enabling the brakingof this shaft by a stop-brake, m, operated by handle 1. The drill-ropedrum Dis held in position by a pawl, i, which may be I disengaged bypulling on its handle is.

The beam K oscillates on or with the shaft It, journaled in bearings onthe lower timbers of the frame. This beam K presses a pulley, Q, inbracket-bearings bolted to it, as shown. 8c The bracket maybe movedalong and the bolt passed through other holes, as shown inthe drawings,to increase or diminish the stroke. The rope S passes from drum D downunder pulley Q, up over pulley T, and thence down to the drill. The ropeU passes from the sandpump reel G over pulley V, and thence down to asand-pump, indicated at W, which is an ordinary slim bucket with avalveatits bottom.

The operation is asfollows: Sprocket-wheelH go and bandwheel I areordinarily disconnected. The beam K being held up against the cam J bythe weight of the drill,theleverlis grasped, holding gear 0 and drum -Drigid. Pawl z is pulled out and brake m allowed to slip, drop ping thedrill a cog or two,as may be desired, whereupon the pawl z is reset.When it is desired to raise out the drill, pressure on the handle gthrows sprocket-wheel H and clutch 0 into connection, passing throughthe revo- 1c lution of the drum D, the pulling in of the rope, and theraising of the drill, the beam K dropping down the instant it isrelieved of the weight of the drill. The sand-pump is then lowered byuse of brake q a up applied to reel G. Thesand-pumpisraised asfollows:Press ure on handled causes the interlocking of the clutch P andband-pulley I, and the reel G is thereby caused to revolve by means ofbelt e, and the rope pulled in and pump lifted.

It will be perceived that both clutclrlevers, both brakes, and thepawl-lever can be operated by one person stationed at the front of themachine, and that the reel-brake can be operated by foot, and thesprocket-wheel clutch by either hand or foot. Operating-levers haveheretofore been extended to the front of drilling-machines, and I do notclaim such feature broadly, but only the particular combinationshereinafter pointed out.

I am aware that mechanism for operating a drill and pump have beenlocated on the same frame and provided with suitable cl utch-levers andbrakes, and I do not claim such combina tion broadly, but only myparticular construction and arrangement herein set forth, and pointedout in the claims, whereby a foot and both bands can be convenientlyused for connecting, disconnecting, or braking the different parts ofthe machine as desired.

Having thus described my invention, what I desire to claim, and secureby Letters Patent, 1s-

1. A wclldrilling machine-Which comprises the drill rope mechanism,including the sprocketwheel H and clutch O, the handle 5 and leverf, thebrake m, having handle Z, and pawl z, having handle K, and the sand-ropemechanism, including the pulley I and clutch P, the compound lever a b0, having handle d, the treadle p and brake q, and intermediate levers,a n, the treadle p and handles d g 70 being all located at the front,twoon the left and two on the right of the machine, and the several partsbeing constructed, arranged, and supported in a frame,substantially asset forth, whereby a foot and both bands can be conveniently used foreffecting the several operations described.

2. A well-drilling machine, which comprises the drill rope mechanism,including the sprocket-wheel H and clutch O, the handle 9 and leverf,the brake m, havinghandle Z, and pawl i, having handle K, the curveddepressing-arm provided with friction-rollers,and the sand-ropemechanism, including the pulley I and clutch P, the compound lever a b0, having handle d, the trcadlep, and brake q, and intermediate leversmn,the treadlep and handles d 9 7c being all located at the front, two onthe left and two on the right of the machine, and the several partsbeing constructed, arranged, and supported in a frame, substantially asset forth, whereby a foot and both hands can be conveniently used foreffecting the several op erations described.
